Open source has gone from being the domain of academic researchers to the forefront of enterprise development and deployment. All of the most significant industrial waves of the past two decades have had open source at their heart, whether it's Linux for the operating system, Android for mobile or JBoss and Tomcat for application servers. In this talk we'll discuss how open source has been the defining medium for software development and where we believe it will help drive the industry in the next decade and beyond. We will look at enterprise middleware as a focus, but the core concepts are applicable across a range of different technologies and sectors.

The digital revolution is driving a substantial change in how organizations should look at their enterprise level technology architectures. They need to mix the new and the old in a meaningful way. This presentation explores the path forward in the context of the Accenture Technology Vision 2014.

If every business is a Digital Business, should all Architectures be Digital Architectures? If so, what is a Digital Architecture, and how does it differ from "non digital" ones? Is it a matter of technology, methodology or marketing & communication? Or all of the above?
If there is such a thing as a Digital Architecture, does it mean that we need Digital Architects? If so, what should they know and do differently?
Talk sheds some light on these aspects, and demystify the "digital" buzzword, explaining what it really means (and doesn't mean), from a technologist's point of view

There have been various strategies to deal with the mainframe's legacy, often focusing on total re-platforming with all the pros and cons. In this talk a different approach is presented, using Hadoop at the core to solve specific performance (and cost) weaknesses. This allows to incrementally improve the data pipeline based on sound architectural principles.

Talk is about the technology trend of "Digital Physical Blur" from Accenture Technology Vision 2014 and will explain it in the context of Wearable Technologies and Augmented Reality. I will show the video of the Philips Google Glass Showcase produced by our Tech Labs and will bring the topic to live with further practical, interesting and relevant examples from the consumer and enterprise space. I will close with the iSight video which gives a look where this could lead us in the future.

Biometrics are the prized "third factor" - "something you are" in the security trinity. Biometrics technologies certainly offer us a vision of a future without passwords, but they also offer so much more - benefits that transcend authentication to deliver value through greater efficiency, better customer services, improved social inclusion, and broader fraud reduction prospects. Talk explores some of those possibilities, and discuss the underlying technologies that will make them possible in our near future.

Talk presents a slightly different point of view on portals that contrasts the widespread belief that they are heavy and complicated solutions. Short trip begins with some buzzwords and quickly passing through the portal standards leads to what today's portal platforms have to offer. Live demo shows how a modern portal like Liferay can solve real problems and deliver solutions faster using standard components, services and developer friendly tools.

In modern applications we often have to weigh different modes of data access against each other, we need to optimize for a "hot" path while keeping our data ready for future evolving. Talk introduces you to different possible patterns for data modelling seen in the wild and when to use them. Going from Key Value patterns optimised for raw speed to document style access. Also comparing couchbase to other database to illustrate the trade offs.

Last year, we saw the beginnings of business transformation based on a digital model. Organizations looking to reimagine themselves in a technology-driven world set forth on their journey to becoming digital businesses. Many organizations were experimenting, while others were making larger investments. But all were counting on technology to fuel their next waves of growth. This year, we see a marked uptick in digital. The Accenture Technology Vision 2014 lays out bold trends that are becoming characteristic of larger enterprises, which have been perceived by some as lagging in converting to digital businesses. While social, mobile, analytics, and cloud still drive these trends, the focus now is on new ways that these technologies are being woven into the next generation of business strategies across every industry. Enterprises are embracing technology in the way they do business and also as a catalyst to create something new - new markets, new products, and new areas of growth and revenues. The change is revolutionary. Industrial companies are becoming customer service companies. Consumer products companies are becoming Internet companies. Energy companies are becoming information companies. And media and entertainment companies are becoming logistics companies.

Open source has gone from being the domain of academic researchers to the forefront of enterprise development and deployment. All of the most significant industrial waves of the past two decades have had open source at their heart, whether it's Linux for the operating system, Android for mobile or JBoss and Tomcat for application servers. In this talk we'll discuss how open source has been the defining medium for software development and where we believe it will help drive the industry in the next decade and beyond. We will look at enterprise middleware as a focus, but the core concepts are applicable across a range of different technologies and sectors.

Talk is about the challenges we faced building an offline-first web application, using the HTML5 technologies AppCache, IndexedDB and File API to store the application's sources and data in the browser.
- Who is master of the data?
- What if schema changes break out-of-date clients?
- How to handle updates of the application?
- How to sync data between clients and server?

Force.com is becoming increasingly popular Platform as a Service solution, offering easy to use User Interface for working with Objects and Records. The challenge comes with more complex user interactions. Human mind is not always very good at working with records when thinking in different terms.
Talk demonstrates how AngularJS can be non-intrusively deployed to Force.com Platform and greatly improve usability. We will show a specific example how management of Customer Account Hierarchy can be made much more productive with our AngularJS component.

In today's responsive world, user experience and application performance is becoming more important than ever. Performance optimization has long been considered a task that requires careful manual "tuning" of several application components, as well as continuous testing. In some cases, the effort involved may outweigh performance gains, and this is when developers must walk the tight rope between benefit and cost. With the advent of automated build tools and task runners like Grunt, automating these tasks has become possible. In this session we will cover examples of some of the most common approaches, as well new and more radical methods including unCSS, combining media queries, bunching up API calls, automatic sprite image generation, and others.

JavaScript development has greatly evolved over the last few years and still keeps evolving so fast that it's hard to keep up. Talk will present some of the latest stuff: ECMAScript 6, Dart, JavaScript on the JVM (Nashorn), Blink vs. Webkit, and so on.

Role of emotions has long been considered as an influential factor for an advertisement to succeed and drive sales. Realeyes provides a platform to measure spontaneous facial expressions of the subjects which are linked to the internal emotional responses elicited by the watched content. This talk demonstrates that the measured expressions can efficiently be used to predict social media popularity which is a key indicator of success of an advertisement campaign. These results can be of great interest to the marketers to understand and evaluate the contents of their advertisements.

Talk is short introduction to Google Analytics. What can you get from the basic implementation. How can you use to improve you website. Where are the limits. Comparing the real world experience of shopping in a brick-and-mortart with e-commerce. Example of using new Google Analytics functionality Enhanced e-commerce to understand the customer journey in its entire complexity.

The Java EE 7 platform has four new components (WebSocket, JSON-P, batch, and concurrency), three that are significantly updated (JAX-RS, JMS, and EL), and several others that bring significant changes to the platform. As you can imagine, a lot of new functionality has been introduced in the platform. In this fast-paced session, you will learn about 50 best features introduced in the Java EE 7 platform.

Red Hat JBoss Fuse is a robust, flexible, and easy-to-use platform to integrate applications, data, services, and devices. The integration platform uses popular open source technologies to provide transformation, routing, and protocol-matching services. It includes Apache Camel, which is an implementation framework for the most commonly used Enterprise Integration Patterns, and also supports extensive connectivity to integrate with different enterprise assets. JBoss Fuse is a robust integration platform that is easy to extend, easy to manage, easy to maintain.

Over the last few years, business process management (BPM) solutions have seen rapid adoption across the enterprise. Innovative organizations are recognizing the value of BPM for improving the efficiency and agility of business operations, and thereby boosting competitiveness and the bottom line.
Late last year, Red Hat launched a new BPM platform, Red Hat JBoss BPM Suite. The offering resulted from an extensive engineering effort to merge our popular business rules management system (BRMS) with BPM technology acquired from Polymita. The result is a comprehensive platform for business automation, incorporating 3 key technologies - business rules, business processes, and complex event processing.

Antlr is one of the most commonly used tools for language recognition in Java. If you ever have a task to parse some text with defined grammar, evaluate mathematical expressions or create a custom domain specific language, Antlr might be one of your first stops for such task. In the presentation we will show basic examples for creating Antlr grammar, generating the parsers for a custom language and running it as a part of your web application.

Talk is about caching from basics to the enterprise use cases. If you are a developer and your applications are slower than expected during this talk you'll get principles and techniques to create faster applications

Open Government Partnership (OGP) is a platform for domestic reformers committed to making their governments more open, accountable and responsive to citizens. Slovakia has been involved in Open Data activities, and is expecting to further promote Open Educational Resources, Open Access, as well as Open Source in the public sector.

Docker and containers are a great way to implement a scalable environment for development and production. Containers don't solve some problems that a platform should have: service registration/discovery and routing, log aggregation, dashboards and health checking, running more than a single process per container and container orchestration in a single node or across multiple nodes. In this presentation I'll take a look at these issues and propose solutions for them and demonstrate through an example based on Cassandra how they can be solved.

Talk focuses on a set of tools to automate the provisioning of (cloud) servers using Groovy libraries and Gradle plugins. We explore how to leverage those to create an infrastructure for building, configuring and testing the provisioning of boxes in the cloud - elegant and groovy.
Java/Groovy developers interested in reusing their existing skills for infrastructure provisioning and learning more about problems encountered
during system operations should come to this presentation.

Red Hat Enterprise Linux OpenStack Platform delivers an integrated foundation to create, deploy, and scale a secure and reliable public or private OpenStack cloud. Combines the world's leading enterprise Linux and the fastest-growing cloud infrastructure platform to give you the agility to scale and quickly meet your business demands without compromising on availability, security, or performance.

You have heard about PaaS (Platform as a Service). You have heard about DevOps. You have probably heard about Docker. You might have heard about Kubernetes. Is there any connection among those technologies? Yes! OpenShift! In my talk we shall explore how your organization can benefit from PaaS and how the future of OpenShift - PaaS by Red Hat - fits into this picture.

Cloud and cloud services are raising on its popularity. In the networking environment, similar revolution approaches with the virtualisation of networking functions. The next step is to virtualise networking infrastructure. Is it possible with Software Defined Networking?
